[vtkusers] vtkAssembly::SetVisiblity(int)

[Eric E. Monson]

Hey Sebastian,

Well, it works for me. Here's a Python example where setting visibility to False gives a blank window, but setting it to True gives a cube and a sphere:

# -------------------------------
import vtk

sphere = vtk.vtkSphereSource()
mapper1 = vtk.vtkPolyDataMapper()
mapper1.SetInputConnection(sphere.GetOutputPort())
actor1 = vtk.vtkActor()
actor1.SetMapper(mapper1)

cube = vtk.vtkCubeSource()
mapper2 = vtk.vtkPolyDataMapper()
mapper2.SetInputConnection(cube.GetOutputPort())
actor2 = vtk.vtkActor()
actor2.SetMapper(mapper2)
actor2.SetPosition(1,1,1)

assemb = vtk.vtkAssembly()
assemb.AddPart(actor1)
assemb.AddPart(actor2)
assemb.SetVisibility(True)

ren = vtk.vtkRenderer()
renWin = vtk.vtkRenderWindow()
renWin.AddRenderer(ren)
iren = vtk.vtkRenderWindowInteractor()
iren.SetRenderWindow(renWin)

ren.AddActor(assemb)
ren.ResetCamera()
renWin.Render()
iren.Start()
# -------------------------------

Maybe there's something else happening with yours? What version of VTK and platform are your using?

Talk to you later,
-Eric
